I want to rebuild my V-6 I got in my Dakota. I was wondering what all I would have to do to hit 400bhp normally aspirated. Any ideas? or is it possable?

wow... 400??? my suggestion is to pray for a V8 to MAGICALLY drop into your system over night... try a blower, nitrous, and lots of money in engine mods. it can probably be done... just might not be worth the money.

400 HP on a NA v6. yea right.
with NOS and a blower maby, but i would stand back ;-)
if you are going to try to build a engine with that much power, obviously money is not an issue. just buy the 408 and run 11's.

For long term life out of the engine, everything is going to have to be forged. Forged parts equal $$$$. The crank is cost you a pretty penny since it will have to be custom (no company makes one yet). You'll need a serious cam which will not pass smog, but you might be worried about that. The beer barrel intake will not cut the mustard which means you'll need a custome one. There is only so much you can port and polish on the stock heads and even then it wouldn't be enough to hit your goal. You might also need custom heads and who knows how much that will cost you. With the limited parts available I do not see anyone hitting 400hp on a newer 3.9 without an S/C or NOS. Well, who knows, with enough money anything is possible. Oh, after you get the engine hitting 400hp you'll need a stronger tranny, driveline, and rear axle. Good Luck.

New camshaft, Full roller system, High compression heads and pistons, Big valves, Computer upgrade, K&N filter, Gibson cat back, Port and polished, Blueprinted motor, HuGE throttle body and bigger injectors. Still i think you will be about 100hp short of 400.
Then add a blower and you will be at 400 maybe.
But it probably will have the roughest idle on the planet. It will be loud. The servise engine light will be lite up.
If i were you i would find a 5.9 and do it to that engine. Would be much easier and engine would handle the improvements much better. Would be a lot easier if you scrubbed the fuel injection and used a carb.

Anything is possible with the right amount of money. But a 400HP normally aspirated V6 is asking a little bit much.
Stick with a good cam, ported heads, modified Intake manifold, headers, TB, and the rest of the standard stuff (but rebuild with forged pistons) and you'll have a screaming V6 just begging for NOS and/or a Blower.
Remember, while the 5.2/5.9L can make much more power than the V6, they're prone to blowing head gaskets after 9# boost. The V6's are much tougher and can easily handle 11# without blowing head gaskets.

So what is the most power someone has built up their 3.9?
I was thinking about getting a 440 and beefing that up. I don't want a 318 cause I think they suck, and I don't want a 360 cause I just don't want one. I think the 440 is my answer instead.

why do you think the 318 sucks? if you think that sucks then the 360 must suck too because its almost the same.
it is illeagle to put a engine into a car that is newer than the engine.
i have seen a 440 put into a 2000 QC, but it was for show only.
good luck

Last time I checked my truck on the dyno:
209RWHP/277RWTQ (01/2001)
That comes out to approximately 250HP and 332TQ at the crank. Now this was around January of this year and that was with the 9# pulley and a 48mm TB.
I'm now running a 50mm TB and 10# boost with a 30HP shot if nitrous. According to the 1/4 mile calculations from Houston (with only a 25HP shot), that puts me right about 233RWHP and 300RWTQ. That comes out to about 290HP and 370TQ...right on par with the extra boost and nitrous. With the 30HP shot, the power is a little bit higher.
Obviously, there's a few other V6 Dakota's running much higher HP figures, but this is with the stock cam, heads, and a mildy modified intake manifold. With the modified heads and custom ground cam...i'll be around 260RWHP and 330RWTQ, but we'll stick her on the dyno to verify this after we're done.

So, here is what I would do with a 3.9:
Engine:
Heads ported and polished. New Intake with the V-8 Throttle body. Bored 30 over with new pistons. Bigger fuel injectors. New distributer with Mopar performance wires, and new Coil. Headers will be a must, with dual exhaust with muffs. What type of power you think I can get out of this?
Tranny:
Keep same Tranny and get it rebuilt. I want to put a nice shift kit in it to. Although I already am able to burn through first gear and into second. I got 170,000 miles on my 3.9 and it still does this, it's funny!

And it's not illegal to put an engine in a car that is older than the car. My friend is putting a 1973 455ci in his 84 Cutlass. If there is a place where a law like that is in effect, I suggest some moving.

Deek is 100% correct on the California Law. This was in effect even back in 1989-1992 when I was BAR-90 certified in the state of CA (Smog Tech).
Kota: About $3000 if you spend it wisely.
Kyle: No need for a distrobutor as they don't work like the older (conventional) distributors. On the injectors, unless you plan on supercharging, there's no need for them as well (19# FMS HighFlow's will work just fine). What you're missing is the biggest key to the HP...the cam. The "polishing" on the heads is useless unless you're running alchohol or nitromethane ("Ported and Polished" is a loosely used term). The porting work will give you some gains but the real HP is in the bowls...clean them up and unshroud the valves as well.

The moment you change your engine to an engine that wasnt designed or never put into the truck like a 440 you turn your truck from PICKUP catagory to HOTROD catagory. Higher insurance and diffrent emitions laws.

Do you drive a white lowered clubcab Dak? I met a Dak with 20s about four months ago at the Malibu Speed Zone, just wondering if its you. The DTOA (Dodge Truck Owners Association) had a get together for some fun racing. Get ready for January, I'll be going to Fontana (1/4 racing) and would like a better Dak turnout. Oh, its DeepDak, don't know how a k (oops) got into the first word.

I have the Deep amethis CC with the Hurst shifter you (think it was you) checked out. At the time my truck was stock height with 17s and few other mods. Now my truck is lowered, Cowl hood, II pro-sport tonneau, with a couple more performance mods.
Did you get that email from Jim? I was surprised to read that he won't be keeping his truck. That is alot of work just to take it all apart in the end.

Stealwings,
Why are you hating? No one here is putting down where you live. I've been from the East to the West and I prefer Cali. Ya, new comers might get "dupped" by some of the girls here, but us locals spot them like an annoying ricer. Looking at your post, it sounds like you got "dupped". Beach=love??? How about beach=adrenline. If you think going to the track is a rush, try handling a 10ft wave!
Eric,
It sounds like his truck is a lease and he is not buying it. Selling yours??? You'll regret it the day you do that! Isn't your truck a 5.2 5-speed?
WRX? If I was to get a ricer, it would be the Acura RSX. I sat in one the other day and it fit me like a glove. I could not get over how comfortable the seats were and how soft the clutch pedal for the 6-speed is. Oh, running the 1/4 in 14.7 stock is not too shabby either.

yea its the 5.2 5speed, and i still dont know if i want to part with it. the seats in the WRX fit like recaro's and running low-mid 14's stock is nice. i have heard on the subaru website, $200 gets you 13.7-13.8. you also cant beat the AWD system.

look man. Dont trade ambition for stupidity. If I were you and I was stuck on a V-6. I would first change the rear gears to about 4.56 - 4.88 or if it is a daily driver to about a 4.11. Then Chip the V-6 and put a after market air filter and hot coil on. Beef up a good tranny to put behind it to put all the power to the ground. Then I would go with a 5 speed and a after market clutch and pressure plate. Then all you need is a bunch of forged parts, a camshaft(s) that turns some RPMs and put me a powerdyne or a vortech supercharger on(with about 10 psi). And a 100 shot of gas would not hurt. Or your other alternative is put you a chevy 4.3 in it with the same mods. A word of advice is to go V-8 all the way.

also, WTF would you want a POS chevy engine in a dakota? they cant even move the S10's out of the way fast enough, and you want to strap it in a heavier dakota??

I'm glad to see all of the interest in V6 performance. You've answered all of my questions here. I own a '93 4X4, 3.9, auto, Club Cab, and the old maxim that more cylinders=more displacement=more power is still true. If you want to make a hot rod out of a 4400 lb. truck, like mine, get a V8. It's clear to see that the 3.9 was only meant to enable the truck to get off the showroom floor under its own power, or Mother Mopar would've based it on the 360 instead of the 318. But, on the other hand, mine has 127K on it, and the oil pressure is good (I use Mobil 1, 10w30, like Mopar Action recommends) and when I cruise the superslabs like I do for a living, it will roll at 70 all day long without working hard (2100 rpm). Unless I'm traveling through the Pennsylvania mountains, then there's a lot of third-gear time. I like the truck, and as far as the engine goes, I hear that for 2004 the new Hemi will be available.
